pplcation filed March 1, 1915. Serial No. 11,133.

' le it known that l. HENRY C. KESTEL., ot

ytoledo. luiras county. Ohio. a citizen of the l'nited States of America. hare invented o new and useful (los-ure Devices. ot which the tollowingr is a speril'ication,

This invention relates to yieldable walled members and the 'forming thereof.

rlhis invention has utility in connection with cup shaped articles or Caps, especially for vessel closures, as t'or bottles in the delivery ot milk and milk products.

Referring to the drawings, Figure l is a fragmentary view in medial Section ot an embodiment of the invention in a milk loottlel closure: Fig. 2 is a fragmentary View of a blank ot the sheetor pulp material; Fig. 3 is a side elevation ot' the cupped blank; Fig. el is a side elevation ot the dented trapped blank; Fig. 5 is a medial section ot the tianged l:upped blank baring;` the dented walls in the eup portion; Fig. G is a 'plan View ot the blank of Fig. 5, 'with the flange 'e-triniuiei'l, and Fig. 'l is a side elevation of the, trimmed flange dented wall cupped blank, with the flange bent against the sinuous or dentedv wall ot the cup of the blank.

ln the torniation o1 this article. the sheet ot' material l. as paper, may be treated to render it susceptible to being reformed, as by moj "'ening'. The circular blank f2 is cut there?` im. rthis blank E2 is cupped to torni the bottoni or stiii'ening' portion l and the annular eup wall l. intermediate the leiwth ot this annular wall i dents 5 may be rormed in this wall to give the wall a sinuous torni in its middle section. The next re-ti'irmation may be the outwardly iang'iiig oit the tree .terminus ot' the wall -l to forni the flange (3. trimming this liange 6 to properly torni liauge T and bending ths trinnned flange 7 bart upon the dented portion ol the wall of the cup to torni the return bend Flange or head 8. To enable the article to better resist attacks in use. it may be waterprooted, as by paratlin coating. The. completed cap now has the main section or eup bottom 23 with the annular wall risingy therefrom in its medial. section oi siuuous rform. The. projections or dents in this sinuous wall are yieldable, or rather elastic. as the* are tough and will return to initial position, eren when compressed considerably. To stillen the annular wall still. more against l-letorniation than the provision of they portion 3, the bead or .flange e is formed integral with the other' elements ot' the cap. Y

ln bringing the eap into closure acting; po sition, it may be readily pressed into position over the lip or bead il ot a or bottle 10, and when so snapped down into holding action, the bottle may be lifted thereby, or may eren be turned on its side or wrong side up. and the contents' still retained in the vessel. There is another automatic feature in the use of the cap haring utility in the handling ot' iquitls or substances anden going volume change under i-arying atmospheric conditions. li'ith milk or writer cooling. or tree/zing, the. exiansion doe. not rupture this rap`r nor torre it out ot bottle closing position.

The diaphragm o may be shifted outward a little so there may be liet by slight seepage between the dents There is accordingly no opening' ot the sel to permit entrance of foreign matter or any occasion to except tothe device in z ny way as butthe most superior sanitary vessel closure. The cap inay be easily and seeurey applied with great rapidity. and in itself. it is substantial and secure against accidental removal, but accessible for positive removal when occasion therefor arises. YWhen the vessel is opened, there is no accumulation ot' lil/th which may wo'k into the vessel in taking oli' the cap. For single service in dairy use. printing u'iay'oecur before the initial moistening.

lVhat is claimed and it is desired to seizure by Letters Patent is:

A coi'er for a lipped vessel embodying a disk provided with an annular flange haring intermediate its extent away from the disk, an endless series ot' yieldahle inwardly eX- tending projections, said. flange having' beyond said projections a return bend stiiiening portion whereby the projections are firmly held to coaet with the vessel lip and yieldably draw the disk tlieretowartl.

In testimony whereof l atiix niy.V signature in the presence of two witnesses.
